Excellent shots! I really like the first and last one as well. HDR can be really fun eh? I prefer the shots that are not overdone and you have done well at that. I do find that in doing HDR it shows the sensor dust a lot more. You can see a few spots in the top left of your last image for example, but that is a very quick fix. I've combined images in the past and been shocked at how much dust I see in the images lol...
